For sports-grade non-infill artificial turf, buyers should pay attention not only to the original fiber strength but also to fiber strength retention after accelerated aging and mechanical testing.
Fiber tensile strength indicates the mechanical strength of an individual fiber.
Fiber strength retention provides additional information about how well that fiber maintains its mechanical properties after exposure to:
- UV radiation
- Heat
- Moisture
- Repeated mechanical loading
- Long-term environmental conditions
For outdoor sports facilities, this distinction is particularly important.
A fiber with high initial strength may not necessarily maintain the same performance after years of outdoor exposure.
Therefore, international buyers should consider:
Initial performance + aged performance + retention rate
rather than relying exclusively on the initial laboratory value.
